Arduino Voice Recognition Module V3
DescriptionVoice Recognition Module is a compact and easy-control speaking recognition board.This
product is a speaker-dependent voice recognition module. It supports up
to 80 voice commands in all. Max 7 voice commands could work at the
same time. Any sound could be trained as command. Users need to train
the module first before let it recognizing any voice command.This
board has 2 controlling ways: Serial Port (full function), General
Input Pins (part of function). General Output Pins on the board could
generate several kinds of waves while corresponding voice command was
recognized.What are the updated features ?We already have Voice Recognition module V2 and it supports 15 commands in all and only 5 commands at the same time.On
V2, voice commands are separated into 3 groups while you training it.
And only one group (5 commands) could to be imported into Recognizer. It
means only 5 voice commands are effective at the same time.On
V3, voice commands are stored in one large group like a library. Any 7
voice commands in the library could be imported into recognizer. It
means 7 commands are effective at the same time.
ExampleHere i will show you an example how to control RGB by voice.1. Recording
We need to send serial command to this module. You may need a USB-TTL module to connect it with PC. Send command 0xaa11 to record. Please refer to the manual for more information.Please notice that :Please record the following voice instrctions in order send command 0xAA21 to import group 1.2. Hardware connection
TXD of Voice recognition Module should connect with RXD of USB-TTL
module or Arduino .
RXD of Voice recognition Module should connect with TXD of USB-TTL module or Arduino .
int redPin = 11; // R petal on RGB LED module connected to digital pin 11
int greenPin = 9; // G petal on RGB LED module connected to digital pin 9
int bluePin = 10; // B petal on RGB LED module connected to digital pin 10
byte com = 0; //reply from voice recognition
pinMode(ledPin, OUTPUT); // sets the ledPin to be an output
pinMode(redPin, OUTPUT); // sets the redPin to be an output
pinMode(greenPin, OUTPUT); // sets the greenPin to be an output
pinMode(bluePin, OUTPUT); // sets the bluePin to be an output
void loop() // run over and over again
com = Serial.read();
color(255,255,255); // turn RGB LED on -- white
color(255, 0, 0); // turn the RGB LED red
color(0,255, 0); // turn the RGB LED green
color(0, 0, 255); // turn the RGB LED blue
color(0,0,0); // turn the RGB LED off
void color (unsigned char red, unsigned char green, unsigned char blue) // the color generating function
the code above to Arduino. Please disconnect TX and RX while uploading
code because uploading would occupy serial interface.4. Result ShowAfter uploading is done, connect RX and TX, and then press RESET button on Arduino.You can see the video on 2Here we will show you how to use the GPIO output to control other device.Step 1First you have to record the voice instruction. Send command 0xAA12 (group 2).Please record the following 5 voice instructions in given note you have to speak clearly.Step 2Connect the device with LEDs in the following way :
Step 3Import voice group 2 by command 0xAA22 or set pin GCH HIGH and pin GCL LOWSpeak voice instruction.Now you could control the LEDs by voice. Product list
